Our local star , sun , is third generation star i . e . it contains heavier elements like carbon , iron and uranium that were created by earlier stars which exploded in a nova explosion when they ran out of their hydrogen fuel 我们的地方星,太阳,是它包含更重的元素象碳由更加早期的星创造爆炸在新星爆炸的第三代星即,钢和铀当他们用尽了他们的氢燃料。
Discovery ' s launch was delayed for two weeks while engineers searched for the cause of an elusive problem with one of its hydrogen fuel - level sensors during the first launch attempt on july 13 “发现”号原定于7月13日发射，但是由于其中一个液氢燃料传感器发生故障，工程师花费了两个星期来寻找造成这个难题的原因， “发现”号也不得不推迟至本周二发射。
Beijing ' s efforts to introduce some forms of green technology , such as hydrogen - fuel - cell buses and solar - powered olympic games facilities , have also been too limited to have much effect , critics say 批评人士指出，虽然北京为引入某些绿色科技付出了努力，例如使用以氢燃料电池为动力的公共汽车以及为一些奥运场馆安装太阳能设备等，但这样的措施非常有限，成效不大。
Longer - term , nanotechnology is likely to make hydrogen easier to produce and safer to store as a renewable energy source . in light of this , most experts agree that nanotechnology will play an important role in advancing fuel cell technology 从长远角度看，纳米技术将使氢燃料的使用和存储变得更加简便作为一种清洁型可再生资源，氢燃料将为汽车行业带来革命性的变化。
Woodcliff lake , n . j . , aug . 16 / prnewswire / - - bmw today announced the launch of the hydrogen 7 pioneer program as it handed over the keys of a bmw hydrogen 7 - - the first hydrogen - powered luxury sedan - - to hollywood actor will ferrell 宝马汽车公司日前推出了作为市场先驱的装载液态氢燃料的氢能7系轿车，这是世界上第一款豪华氢气动力轿车，它的钥匙已经交给了好莱坞影星威尔?法瑞尔。
As early as in 2001 , china will have a new energy to the development of a clear plan , which was to petrol vehicles as a starting point , the hydrogen fuel cell vehicles into the goal , as the electric car was the focus of corporate funds to support development projects 早在2001年，中国新能源车就有了清晰的发展规划，即以汽油车为起点，向氢燃料电池车目标挺进，其中电动车被作为企业开发的重点资金支持项目。
That ' s not a concern for autos that burn gasoline or diesel , but for a future in which vehicles run on nonpolluting hydrogen , adequate driving range remains a real roadblock [ see “ on the road to fuel - cell cars , ” by steven ashley ; scientific american , march ] 这可不是指燃油汽车，而是指未来以无污染的氢气为动力的汽车；不过，续航力不足是这种车目前最大的困难（参见2005年4月号氢燃料电池车乾净上路） 。
